To all whom t may concern: Y Y

Be it known `that I, GEORGE H. DAY, citizen oi the United States, residing at Cuba, in the county of Fulton and State ot' Illinois, have invented certain new and useful Improvements in Apparatus for Continuously Separating Juices from Materials, and vdo hereby declare that the Jrollowing is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it app'ertains to ina-'ke and use the same.

This invention relates to an apparatus tor separating ljuices from vegetable and other products.

It pertains particularly to expressing juices from vegetable products such as fruits and the like or such other materials as can be lso treated,and to an apparatus for the continuous handling oi the same.

The main obj ect ot the invention is to vprovide an apparatus ot the nature described constructed `and arranged so that it can 'be operated to express juices from materials of various 'kinds ina'continuous manner.

Another object is to provide an apparatus for the continuous extraction of juices from fruits of .all kinds and trom all other products ot whatever nature, preferably first reducing the material to a pu'lpy mass in any usual manner, del'iositingr it upon an endless carrier ot'suita'ble loosely woven fabric, then carrying `the pulp between pressure rollers for tor'cing out or expressing the juices, the resulting residue or pomace being delivered from the carrier automatically and without attention, all ot the juices being deposited in a suitable receptacle underlying practically the entire carrier.

To the end that my invention may be understood, I have provided the accompanying drawings, wherein, j

Figure l is a plan of the apparatus showing my invention;

Fig. 2 is a side elevation ot the same in part section;

Fig. 3v is a cross section of the apparatus on line 3 3, Figs. l and 2, much enlarged; Fig. 4t is a cross section on line 4-4, Figs. l and'2,.also much enlarged; y

Fig. 5 illustrates, in perspective, certain portions shown in the preceding iigures; and, Fig. 6 is an elevation of parts shown in Fig. 5.

In my type of apparatus it is my purpose to deposit the materials upon an endless belt or carrier which is made to travel between pressure rollers, for example, in a continuous manner as has been stated in the objects, the liberated juices passing through the Jfabric ot the carrier being caught by a receiver, the pomace being also continuously discharged and without attention on the part oi the operator, the apparatus being wholly contiruous in itsfaction.

In addition, the carrier in its continued travel is made to receive constant treatment trom an automatically operated beater whereby any adhereing particles, or any inc.- terials that may tend to clog the meshes or' the carrier are removed so that the latter is always yin condition tor proper work. But this will be more readily understood trom the detail description following.

There is viirst provided a trough-like receiver l having at the top and bottom, at each end, rollers '2, 8, l and 5, suitably journaled in brackets G, tor example, Fig. 5, which rollers lie parallel lto the end walls ot such receptacle. An endless belt or carrier 7 of fabric, such as cloth, 'for example, ot a weave that will readily permit passage therethrough of the juices, is 'trained over the rollers.

lith'in the receptacle at lsubstantially the middle of its length, 'tor example, is a pair of upright pressure rollers 8, Fig. 3, journaled in suitable cross trainings 9 secured to the receptacle,the carrier being supported by and arranged to pass through these rollers in a Jfolded condition as will be more fully explained later.

Stationed above the carrier at one end ot the receptacle is a hopper l0. Itotatable within said hopper is a grinding or material reducing cylinder l1 suitably journaled. l2 is a pulley on the shatt ot the cyl inder to be driven trom any suitable power, not shown. The described hopper' ,overlhangs one end ot the carrier so that the material reduced 'therein will be discharged upon it.

13, lli indicate two pairs of supporting rollers tor the carrier stationed between the hopper and the pressure rollers. These are mounted upon and journaled in suitable supporting trames 15, each pair being disposed inthe torm ot a V.

1G, 17 are similar pairs of rollers lying between the pressure rollers 8 and the horizontal roller 3 at the end ot the receiver. 18 indicates a pair ot boards erected between said hopper and the adjacent supporting y rollers 13 and between the latter and neXt lally doubled upon itself pair of the rollers 1K1. The inner surfaces are preferably corrugated vertically aspat 19, Fig. 2, the carrier adapted to drag over such corrugations. y Y

It is observed that said carrier as it leaves the roller 2 in its flat belt-like form is graduuiitil upon reaching the rollers 8 the doubledl portions lie parallell to one another and after leaving said rollers the carrier again opens to and assumes the fiat form as it passes to, upon, and over the roller 3. This is caused by carrying the edges of said carrier toward one another. Thatis to say, the roller 2 and roller 3 Fig. 6, are furnished at their ends with a groeve 2O and the brackets 6 in which the rollers are eurnaled each carries a grooved roller 21 overlying the portion of the rollers having said grooves and in each edge of the carrier is preferably suitably secured a heavy cord or cable 20 adapted to be held iii the inclosiire formed by the described grooves and the .said rollers. Likewise the upper ends of the pressure rollers S are grooved at 22 to hold both said cords or cables and as said rollers lie close together the said cord or, cable of each edge of the carrier is held within said grooves,`

which cords or cables must, of necessity, be

brought together, due to theclose relation and position of the rollers, the carrier itself hanging between the rollers. The rollers 13 and 14, 16 and 17 are likewise provided with grooves 23, F ig. l, and adjacent each vis a grooved roller 2/1 mounted on the supporting frames therefor so' that i the separate cords or cables are positively supported andthe carrier is thus suspended in its working position.

26 represents a gear on each of the pressure rollers S. rlhese mesh with one another and the rotation of one of them imparts an opposite direction of rotation to the other. The shaft of one of the rollers is provided with a beveled gear 2T, and 28 is a beveled gear meshing therewith secured upn a shaft 29 having its bearings upon part of the supporting frame 9. y

At one end the shaft 279 carries a pulley 3f).

which, through a belt'3l, drives a pulley 32 on the shaft of the roller 3. 33 is a gear-box mounted on one of the frames 9 and 34 isV` Va gear on the shaft 29 within said gear-box.

35 is a stub-shaft extending from the gearboX'and provided with a pulley 36 which, through a belt 3T, is drii/'enfrom a pulley 38 on the shaft of the reducing cylinder 11.

l Though not shown except in dotted lines in Fig. 3 suitable gearing is included within the gear-box by which changes in the speed of the shaft 29 may be made with reference to that of the reducing cylinder which is constant.

' Vstretch of the carrier 7.

Y Ithas not been thought necessary to illus-. trate the speed changing gear in detail since it is well known.

Suspended below the receptacle 1 is a series of rollers 39 supporting the lower 40 is a pulley on the described shaft 29 which, through a belt Ll1, drives a pulley 42 on a shaft 43 journaled in suitable hangers 44, said shaft being suspended beneath the lower stretch of the earrier. The hangers are furnished with an extension 15, but one of which is shown, Figs. 2 and 3, within whichis journaled a rock-shaft 16 provided with a beater-arm lll'. 48 is an arm on the rock-shaft and 19 is a cam on the .shaft 13 to engage with the same.

rlhe operation of the apparatus is as follows: n p

As the edges of the carrier are gradually broughttogether between the described pressure rollers 8 the reduced material delivered pon said carrier is inclosed between the folds of the latter and carried through said rollers, the juices being forced out upon and through the fabric into the receiver' beneath. rlhe pomace as it passes away from the rollers is loosened from the carrier as the latter now opens in changing its form as it passes over the rol-ler 3. The caked pomace is lbroken up by this unfolding action of the .carrierand upon passing with the latter carrier is now free of the bulk ofpomace and those parts that have held the same travel `back to the receiving and pressing position for further work. f

The power transmitted to the pulley 12` besides driving they reducing cylinder rotates the pressure rollersS in a Lproper direction toadvance the carrier while at the same time the roller 3 assists the movement of the carrier through the belt 31 or its equivalent.

In order that the material to be treated shall not be fed too fast between the pressure rollers or thatthe bulk carried to said rollers shall not be in excess of what can be properly handled, I l have provided the mentioned speedchanging gear-box 33 by which theoperator may change the speed of the carrier with respect Vto the speed of reduction of said material so that it may be made to travel faster or vslower according to the amount of material created. However, the speed of the cylinder may be changed instead with vrespect to the travel of the carrier, if desired, since either method may be adopted. rlhe mesh ofthe fabric of which the carrier is` composed Vis such that the juices will readily pass therethrough. This is aided by using the corrugated boards 18 with which the carrier runs in contact. The corrugations will keep the cloth more or less free of adhering Vmaterial and aid in keeping the weave of the fabric open. These boards and the several pairs of rollers described properlyfsupport the fabric and prevent too great strain thereon occasioned by the weight of material.

After the bulk of pomace has kbeen .discharged over the roller 3 as described the carrier is subjected to the beating action of the beater 47 of the rock-shaft 46. That is to say, at `each revolution of the cam 49 in its rotation with the shaft 43 said cam strikes and depresses the arm 48 of said rockshaft, resulting in the extension 47 being thrown up against the carrier blow after blow with considerableV force whereby to dislodge any adhering portions. The meshes or weave of the carrier having passed over the several rollers after the discharge of the pomace and having been subjected to the said beating action together with the dragging action over the corrugated yboards will be in proper condition for receiving further materials for continued action.

lt is required only that thematerial to be treated be fed into vthe hopper, the subsequent treatment requiring no manual exertion after the determination of the relative speeds of the reducing cylinder and carrier with respect to the amount of material being treated. l

lWhile l have shown and described a structure for continuous treatment of materials, changes may be made that will best serve the purpose.

Trlaving thus described my invention, I claim l. ein apparatus of the class described, including in its construction an endless beltlike carrier of fabric, a pair of spaced horizontally disposed rollers over which the carrier is trained, a pair of vertically disposed rollers stationed between the horizontal ones and toward and between which the carrier folded upon itself is adapted to travel, and spaced pairs of members disposed between the horizontal and said vertical rollers, the members of each pair being inclined at an angle to one another in oppo site directions, and supporting the carrier, the angle. of Vinclination of said members more nearly approaching a vertical position as their positions are closer to said vertical rollers.
